99 Club Studio v1.30.1

99 Club Studio v1.30.1

Small review patch following hands-on testing of v1.30.0 Number Patterns & Structures.

• Arithmagon diagonals are now sparse/non-crossing and visually quieter.
• Magic bow-ties now use only straight marked lines and avoid excessive repeated values.
• Factor Pair Webs explain their notation more clearly, show two distinct factor-entry boxes per spoke, and provide a first-web starter pair outside Challenge difficulty.
• Sum & Product Diamonds keep labels/nodes inside their drawing bounds in browser and direct PDF.

No intentional changes were made to the public 99 Club generator, Custom Worksheets, vocabulary/crosswords, Random Pack, personalisation or unrelated Games engines.
